Abstract
An apparatus for communicating signals across a wellbore barrier defined by a first flow completion system component positioned at an upper end of the wellbore and a second flow completion system component mounted within the first flow completion system component includes a first wireless node which is mounted on the first flow completion system component on a first side of the wellbore barrier, the first wireless node being configured to be connected to an external device, and a second wireless node which is mounted on the second flow completion system component on a second side of the wellbore barrier, the second wireless node being located generally opposite the first wireless node and being configured to be connected to a downhole device. The first and second wireless nodes are configured to communicate wirelessly through the wellbore barrier using near field magnetic induction (NFMI) communications.
